UNITED STATES PATENT OFFICE.

IMPROVEMENT IN TUG-BUCKl- ES Specification forming part of LettersPatent No. 39,734, dated September 1, 1863.

To all whom it may concern:

Beit known that I, NELsoN H. HOWARD, of the city of Beloit, county ofRock, and State of Wisconsin, have invented a new and useful Improvementon a Tug-Buckle; and I do hereby declare that the following is a full,clear, and exact description of the construe tion and of the operationot' the same, reference being had to the annexed drawings, making apartof this amended specification, in which- Figure l is a perspective viewof the buckle with my improvementapplied. Fig. 2 is a view of the edgeof the trace or tug which is used with and in connection with theimprovement to said buckle. Fig. 3 is a view of the whole trace or tug,representing the rise or swell in the tug, which bears against myiinprovement--to wit, the roller or bar passing through the buckle inplace of and substitute for a tongue. Fig. 4 is a view of the bucklewith the improvement attached, showing the bar or roller and the leveragainst which the tug or trace bears. Fig. 5 isa view of the buckle,representing the edge view of the bar or roller and the lever.

In the several figures the same part of the buckle and improvement isrepresented by the same letter.

A represents the roller or bar against which the swell in the tug(marked O) bears in connection with the lever B, thus holding the tugfast between the said bar and lever. This may be fast or roll in thebuckle.

`Letter B represents the lever passing under the tug, and pressesagainst it more firmly as the tug is drawn tighter by any power.

Letter C represents the rise and swell in the tug, which is made byleather or other substance being formed in the construction of the tug,being of the form of a wedge.

The design and effect of this improvement is to save the tug or traceentire and save the necessity of cutting a hole in the tug or trace fora tongue of any kind. Its operation is to press against the tug or traceas it passes between the lever on the under side and the roller or barou the upper or outer side of the tug, bringing the tug at the point ofthe rise or swell firmly against the roller or bar, and the greater thestrain or `draft upon the tug, the rmer the tug at this point pressesagainst the roller or bar.

And I, NELSON H. HOWARD, claimas my ,invention- The lever, as abovespecied, as applied to and in combination with the roller or bar, andthe rise and swell in the tug, as above represented.

N. H. HOWARD.
